I'm not an expert but probably this is not the species you suggest, cause in R. semicolorata the forewings should be hyaline and the femur has a brown streak on the centre.
I'm sorry, I don't know which of the other species it may be.

I'm not an expert too, but the wings, maybe, are of a "preadult" specimen.
I know the mayflies are the only insects that can fly before the last moult (and this is wonderfull for me) and their wings are opaque until it.
